no such file or directory error in comparing two files in bash script

Question

I'm very new in bash script and I wrote a code to compare an entered file with the files in a directory named new2 but i get the following error:

line 8: [~/new1/file1: No such file or directory

here is my code:

input=0
while true; do
        echo "enter a file name from directory new1 to copy it to directory new2 "
        echo "or enter ctrl+c to exit: "
        read input
        i=0
        for F in $(ls ~/new2/) ;do
                if ["~/new1/$input" -ef $F] ;then
                        i=1
                        break
                fi
        done
        if [ $i -eq 0 ];then
                mv ~/new1/$input ~/new2/ 
                echo $input "moved succussfully"
        else
                echo "file exist"
        fi
done

can any one help me to fix this? thanks in advance!

Answer 1

if ["~/new1/$input" -ef $F] ;then

您需要在两个方括号前后放置一个空格

if [ "~/new1/$input" -ef $F ] ;then
